Hacker News Reader

For a practical example of this technique used in JS take a look at libraries like htm and lit-html: https://github.com/developit/htm

(PEP co-author here) The htm folks did a Python implementation: https://pypi.org/project/htm/

It required a janky workaround for the absence of this PEP: https://pypi.org/project/tagged/

I used these to investigate ideas about component-driven development: https://viewdom.readthedocs.io/en/latest/

How is that a Janky workaround? It's not particularly ugly or verbose, nor does it seem to violate any python tenets.
